3 Claims.

The presentinvention relates to a structure such as may be broadly alluded to as an improved ventilator construction wherein the specific s tructuralimprovements pertain to an .5 oscillatory louver or shutter having means at opposite ends for coordinated adjustment and locking purposes.

I am, of course, aware, that. it is not new to ,rnount one or more louvers or slats in a support forosc illation. Itis perhaps appropriate to say therefore, that the invention pertains to a structure including one or more oscillatory shutters having progressively or intermittently operable means at opposite ends, the means at one end serving for rotary regulation and the means at the opposite end to fix or retain the shutter in the position to which it has been adjusted.

One structural feature of the invention has to do with the adoption and use of a hand controlled slidably mounted trigger unit, this being cooperated with detent equipped trip and actuating means on the journal of the shutter, whereby to provide what is hand controlled substantially automatic oscillatory tilting of the shutter for variable ventilating. purposes.

Afurther featureofthe invention is directed toward the mutually cooperablefastener or retaining means associated with the opposite end journal of each shutter or louver, the means at opposite ends being so coordinated asrto possess matching and mutual dependent relationship.

Other features and advantages willv become more readily apparent from the following de-. scription and the accompanying illustrative drawings.

vIn the accompanying drawings, wherein like reference numerals designate like parts throughout the views: s 1

Figure 1 is a front elevation of what may be generally called a window having multiple slat or louverventilating means, the features of this invention being associated therewith to open and close the louvers. l

Figure 2 is a horizontal section on'the plane of the line 2-2 of Figure 1.

Figure 3 is an enlarged fragmentary vertical section which may be said to be on the plane of,

the line 33 of Figure 2.

Figure 4 is a horizontal section occurring approximately on the plane'of the line 4-4 of Figure 3, partsbeing in section and elevation.

Figure 5 is a fragmentary detail section and elevational view showing the spring means and 55. journal at the end of one of the slats or louvers.

Figure 6 isa view similar to Figure 3, the sections being vertically disclosed and approximate.-

so Figure 8 is a horizontal section which may be 1938, Serial No. 183,736 (01. 98-110) said to be taken on the plane of the line 8--8 of Figure 6.

Figure 9 is a section on the line 99 of Figure 8.

Byway of introduction to the detailed description it is to, be pointed out that the features forming the chief novelty to be hereinafter claimed are such as to be restricted to use to a single oscillatory slat, louver or shutter. In the drawings, for sake of more appropriate illustration, the inventive concept is illustrated as being embodied in a full-sized window construction having a plurality of slats.

In the drawings, in Figure 1, the numeral l0 may appropriately identify a door frame, a window frame or the like having an inner special adapter frame I l to accommodate the adjustable slats or louvers 12. As shown to advantage in Figure 2 the vertical hollow stiles of the frame structure I I are differentiated by the numerals l3 and I4. Thus these parts serve as casings for the mechanism forming the adjusting and retaining means for the various slats. It will be observed that the vertical stile or casing M has in its outer face a longitudinally elongated slot l5. The corresponding face of the other stile I3 is imperforate except for the point which serves to accommodate an operating knob hereinafter described. 7

In order to simplify the description it is to be pointed out that the slats l2 are of appropriate dimensions and construction. Each slat; has supporting and adjusting trunnions or journals at opposite ends. The journal at one end as shown to the right in Figure 2 is denoted by thenumeral IS. The journal at the opposite end is differentiated by the numeral IT. A collar I8- is fixedly mounted on the journal I6 as brought out to advantage in Figures 6 and 8. The peripheral portion of this is formed with three notches of predetermined positions and shape. These notches constitute keeper seats and are distinguished 'by the numerals I 9, 20 and 2!. Confined in the casing and cooperable with the various notched collars will be found an operating bar or rod 22. This is slidably mountedon an attaching bolt 22* as shown to advantage in Figure 6. The boltis surrounded by a coiled return spring 23which serves to maintain the substantially wedge shaped detents or keeper lugs '24 out of engagement with the keeper notches I9, 20 and 2|. These detents 2 4 are simultaneously moved into and out of engagement with the keeper notches by a single control button. The button 25 is of appropriate construction and has its shank portion 26 suitably fastened to the. detent control bar 22. The shank is also provided with a block-like retention ,element 2'l slidable in a correspondingly shaped slot in the web 28 of the casing.

In order to give utility to this single button controlled looking or retaining means, particularly the selectively usable keeper notches 9, 20 and 2!, it is necessary to provide adjusting means of the form, or an equivalent style, shown to advantage in Figures 3, 4 and 5.

Referring first to Figure 5, it will be observed that the apertured trunnion is here provided with a hole 29 to accommodate a slidable actuating pin 30 (see Figures 3 and 4). This pin mounted in the journal, is in effect a trip or rocker arm for the trunnion. One protruding end thereof is provided with a Washer 3! held in place by a pin 32, there being a coiled spring 33 interposed between the washer and trunnion and surrounding the trip pin 30. The opposite protruding end of the pin is formed into a head 34 and this terminates in cams 35 and 36. Extending at right angles, and located on diametrically opposite sides of the head 34 are detents 3'! and these are selectively engageable with the three retaining bends 38 in the longitudinally bowed flat springs 39. As brought out to advantage in Figures 3 and the free ends of the retaining strips 39 are suitably anchored and held in place as indicated at the points '30. The strips are arranged in parallelism and the head 3d'sweeps in an arcuate path between said strips 39. Consequently, we have here a selectively adjustable trip or resilient latch means designed to oscillate the slat so that it may occupy a full closed position, a full open position, or a part open position, depending on visibility and ventilation required.

A manually slidable trigger unit denoted generally at 4!, is employed for the purpose of rocking the adjusting trip device just described. This unit 4! is slidably mounted in the slot !5. Hence, it may be moved to a position to adjust just one of the slats or more than one, depending on the circumstances required. That is to say, it is possible to maintain some of the slats closed, to open others full and others part-way. Consequently, the device 4! is in the nature of an adjusting shoe and it in fact, includes an appropriate slide or shoe 42 slidable in the slot. The part 42 is provided with a socket to accommodate the spring pressed trigger. The head of the trigger'd3 is located in the casing to coact with the aforementioned cams 35 and 36. The retractable spring means M! cooperates with a socket in the slide #52. The shank of the trigger 45 is secured by a pin 46 in the hand grip 41, the latter part being located on the exterior of the casing for convenient use. As shown in Figure 4, the trigger includes a yoke whose fingers 48 ride in contact with the convexed and bent portion of the aforementioned retaining strip 39.

In operation the invention functions as follows: By sliding the device 4! from the upper position seen in Figure 1 down in the slot !5 to a position opposite the trip means as shown in Figure 3 it is obvious that the nose 43 of the releasing trigger is engaged with one of the cams 35 or 36, as the case may be. Thus, the downward sliding movement of this part serves to oscillate the trip pin and the trip pin in turn adjusts the trunnion I! on which it is mounted. The detent pins 3! engage in the retention seat 38 in the retaining strip 39 to hold the trunnion in the position to which it is thus moved. When the desired degree of adjustment is attained to move the slat to either part open or full open position, the knob 4'! is grasped and pulled out so that any further sliding movement of the device 4! enables the trip 43 to swing clear of the lugs 35 or 36. This device 4! may be operated either downwardly or upwardly to open or close the slat through the instrumentality of the trip means thus described and constructed.

The coordinated locking means on the opposite end can be brought into play to lock the slat into position to which it has been moved. All that is necessary is to force the knob 25 in. This presses the strip 22 in against the spring 23 and engages the lug with one of the aligned keeper notches I9, 20' or 2! as the case may be. When the trip 22 is forced in the button or knob 25 is turned so as to'dislodge the retaining element 2'! from its slot in the casing and to place it crosswise of the slot on the interior of the casing.

It is thought that the description taken in connection with the drawings will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.
